Answer:
Therefore, each person should pay $9.21 for dinner and the tip.
Explanation:
To calculate the amount to leave for the tip, you can first determine the total cost of the tip by multiplying the cost of the dinner by the tip percentage: $31.85 * 0.15 = $4.78Then, you can divide the total cost of the tip by the number of people in the group to determine the amount that each person should contribute to the tip: $4.78 / 4 people = $1.19So, each person should contribute $1.19 towards the tip. If you want to split the bill evenly, you can add this amount to the cost of the dinner and divide by the number of people to determine the total amount that each person should pay: ($31.85 + $1.19) / 4 people = $9.21
